Based on everything I have read, the trick to travel is as long as you’re in a pressurized plane (and most commercial jets are), don’t hoist your luggage, don’t carry luggage over 30 pounds, and don’t do anything that would make you grunt or hold your breath; you should be okay. Holding breath while lifting something heavy is a natural reaction and it spikes the blood pressure. It’s called the Valsalva maneuver. it raises your blood pressure sometimes as much as 200/100 or higher (in the moment). Do everything you can to keep your blood pressure down and your stress levels down. I would talk with your cardiologist or cardiovascular surgeon regarding any other concerns you have about travel. sometimes high elevations raise blood pressure and heart rate. I’ve been told to keep my heart rate below 130 when exercising and 70 at rest. The lower the better. Some folks go on beta blockers to make sure it stays low. Because of the mechanical nature of 60 beats a minute ( plus) against the weakness in the aorta the lowest heart rate you can have is best. also, if you’re traveling, you might want to get a piece of medical jewelry that says you have an ascending aortic aneurysm because that way if something did happen, they wouldn’t treat you for a heart attack and maybe Realize too late, that your aneurysm was the issue……What a cool monitoring system you have. I like that. We don’t have anything like that in Hawaii ( that I know of).
